Kind of like plugging a toaster onto your battery. It will draw a lot of juice off the battery in just one test with smaller batteries so if they are weak you will know it fast and they will likely need a recharge afterward. I use it for 4 and 8 D size batteries for starting large diesel engines. I would suggest a lighter amp load tester for what you are doing. Something around a 50 amp range.Hope this helps.Paulpaulmgriswold@aol.com **Q: So this would tell you if a car battery is working properly Etc?** A: It puts a load,like you're trying to start your car,on the battery, and will tell you if the battery is bad. Most batteries last 5 to 6 years cheaper ones less so if it's old just buy a new one But if it's newer you might want to check it before buying a new one. The battery has to be charged though, you cannot check a dead battery , so unless you have access to a battery charger this won't help you. **Q: will this work on 8 volt golf cart batteries?** A: Hi Cabo, It might as it has scales for 6 or 12 volt. It would read a little high on the 6 volt scale when checking 8 volt. I can't promise it will work though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exelente para lo que lo uso *by M***L on 20 March 2025* Exelente producto ### ⭐⭐⭐⭐⭐ A Great Tool *by L***E on 16 February 2026* I love this tool.
